Answer:
y=-x-6

Explanation:

The formula for slope-intercept is
y=mx+b, with
m representing the slope,
b being the y-intercept, and
x and
y representing inputs and outputs of the line.

To write the equation of a line in slope-intercept form, you need two components:

1. The slope (
m), which describes the steepness and direction of the line.
2. The y-intercept (
b), or the point at which the line intersects the y-axis.


There are two methods to find slope. The first is by using the equation
m = (x_(2)-x_(1))/(y_(2) -y_(1)), with
(x_(1), y_(1) ) and
(x_(2), y_(2)) being two points on the line. In the second method, you look at the graph and find the rise over run (
(rise)/(run) ) for two points on the line.

In this instance, let’s use the formula. The two points on the line I’ll use (you can choose any two points) are
(0,-6) and
(-6,0). Input them into the equation and you get the following:



m=(-6-0)/(0- (-6))


m = (-6)/(6)

m=-1

To find the y-intercept, look on the graph and find where the line intersects the y-axis, or the vertical axis. The point at which the line intersects the y-axis is
(0,-6); therefore, the y-intercept is -6.


Input the slope and y-intercept into the equation and you get the following:
y=-x-6. This is our finial answer.
